ALONZO GRIGGS, OF WHIT STOR, NORTH CAROLINA.

cHURN.

Specification of Letters Patent.

Application led October 7, 1908.

To all whom it may concern:

Be it known that I, ALONZO Gardes, a citi- Zen of the United States, residing at White Store, in the county of Anson and State of North Carolina, have invented new and useful Improvements in Churns, of which the following is a specification.

This invention relates to churns, and particularly to mechanism for operating churn. dashers of the reciprocatory type, the object of the invention being to provide a simple, efficient and easily actuated type of operating mechanism in which the parts are combined and arranged in a novel manner to secure simplicity of structure with maximum strength and durability.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a vertical transverse section taken on the line 1-1 of Fig. 2. Fig. 2 is a vertical front to rear section taken on the line 2--2 of Fig. 1. Fig. 3 is a horizontal section taken on the line 3--3 of Fig. 2. Fig. 4 is a rear elevation of the upper part of the frame and the gearing, a part of the fly wheel being broken away to better show the construction.

The frame work of the churn comprises four uprights or corner posts 1, a bottom platform 2, and suitable bars connecting the corner posts at their upper ends, as hereinafter described. The corner portions of the base of the frame are provided'below the platform with wheels or rollers 3, by which the apparatus may be conveniently transported from place to place. The churn body or receptacle 4 is adapted to rest upon the platform and to fit at its lower end within a suitable annular retainer 5, by which it is held in position.'

The posts 1 at each side of the frame are connected by upper and lower side bars 6 and 7 and intermediate side bars 8, .and the corner posts at each side are connected at front and rear by cross bars 9 and 10 disposed in the same plane as the intermediate cross bars 8. The bars 6 are connected in turn by a cross bar 11, the bars 7 by a cross bar 12, arranged in alinement with said bar 11, and the bars 8 by a cross bar 13 arranged in rear of the vertical lane of the bars 11 and 12, forming a simp e, strong and durable frame structure at the top which is adapted to support the operating parts in a simple and effective manner.

The churn dasher 14 is mounted to reciprocate vertically in an opening 15 in the churn receptacle and the upper free end of its rod 16 is adapted to fit within the lower end of a sleeve or collar 17 mounted upon the lower end of a vertically reciprocating rod 18, said collar or sleeve being provided with a set screw 19 to detachably couple the rod 16 thereto, whereby the dasher may be readily and conveniently connected with and disconnected from the operating mechanism.

The operating` rod 18 is mounted to slide in bearings 2O on the rear faces of the cross bars 11 and 12 and carries a longitudinally slotted transverse bar 21, the slot in which bar receives a crank pin 22 on the front face of a disk 23, whereby when said disk is rotated continuously in one direction the pin will .travel in the slot of the bar 21 and vertically reciprocate the rod 18 which will transmit corresponding motion to the dasher.

' The disk 23 is mounted upon the forward end of a countershaft 24 journaled in bearings 25 on the cross bars 1() and 13. On the outer or rear end of this shaft is mounted a fly or balance wheel 26 anda pinion 27. The pinion 27 meshes with a transmitting gear 28 mounted on a stub shaft journaled in a bearing 29 on the bar 10, and the gear 28 in turn meshes with a gear or pinion 30 on a drive shaft 31. The shaft 31 extends at one side of the center of the frame from front to rear thereof and is journaled in bearings 32 on the bars 9 and 10 and pro vided at its forward end with a crank handle 33 or any other suitable type of operating device. By this construction the shaft 31 may be driven and will in turn communicate motion through the train of gearing described to the countershaft 24, a uniformity of motion being maintained by the fly wheel, and the countershaft will in turn drive the disk 23, the crank pin 22 of which will operate in the slot of the bar 21 and impart a vertical reciprocatory movement to the operating rod 18 and dasher 14, as will be readily understood.

lt will of course be understood that in the operation of churning, the milk or cream is placed in the receptacle 4, the cover and dasher applied, the dasher rod coupled to the operating rod 18, and the operating mechanism then set into action. At the end mail of the churning operation the dasher is disconnected from the operating rod, leaving` the same and the receptacle free for removal to Complete the process of gathering the butter, ete. The wheels or rollers 3 addr-rpt the apparatus to be Conveniently rolled from place to platee, as circumstances require, thus adding to the eonvenienee of the mechanism.

It Will be observed that the construction of the upper part of tlre traine is sueli as to provide for the rni fastening' ol ell ol the elements thereof together, and for the secure mounting of tlie parts of the gearirm', without complicating the structure, the arrangement of the Cross eers forming the support-s for the elements of the gearing' also serving to transmit the strain so that it will be equally sustained by all of them, thus enabling the apparatus to be constructed et e compera,- tively small cost.

Having' thus ulljT deseribed the inventioi'l, what is claimed es new is:

A churn comprising :t reetm'igulzir irfune embodying corner posts, :t supporting' platform connected with tlie lower ends of the corner posts, upper, lower and intermediate side bars connecting the upper ends of the posts at each side of the freine, front :rnd rear cross bars connecting the posts at front and rem' of the freine, said Cross liars lwiirr arranged in tlie horizontal plaine of ille intermediate side bers, upper mid lower cross bers connectingr tlie upper and lower side 1oars :rnd provided with bearings, en intermediate eross bar arranged, in rerir el' the plane of sii-id upper und lower ross lmrs and connecting the intermediate side lmrs and provided with at bearing, :in operel'fing rod mounted to reciprocate vertirziltv in the bearings on tlie upper :rnd lower cross lmrs, :t Counter-shaft jeurnziled in bearings on the intermediate und ree-r cross lmrs, en operative eoinieetion between seid rod :ind counterslial't, L pinion upon seid reenter-.sliuit, :1`
